AUTHENTICATING CONTENT VIA LOUDNESS SIGNATURE
Abstract:
A method for authenticating content via loudness signature includes receiving an input signal comprising a) an audio signal of the content and b) metadata including data indicating remotely measured loudness of the content, measuring loudness of the audio signal of the content to obtain a locally measured loudness of the content, and comparing the remotely measured loudness of the content to the locally measured loudness of the content to obtain an authentication indication based on the comparing.
